Fig. 3 A show the user interface schematic diagram of the acquisition image content according to the application one embodiment.Fig. 3 B are shown
The interface schematic diagram of the display picture of one embodiment.As shown in figures 3 a and 3b, when user operates to control 301,
Step S201 can obtain a pictures and be shown in the preview window 302.Step S201 can be in response to playing duration control
The operation of part 303, determine the playing duration of picture.Step S201 can obtain in response to the operation to word input control 304
The text information related to picture in the preview window 302.In other words, text information is the supplementary notes to picture.Fig. 3 C are shown
According to the schematic diagram of the acquisition audio-frequency information of the application one embodiment.For example, step S201 can be in response to control 305
Operation obtain the audio (be, for example, background music) being locally stored.In another example step S201 can be in response to control 306
Operation, record a section audio content.The audio content is, for example, the aside for being directed to picture in the preview window 302 and recording.
In yet another embodiment, step S201 can obtain one section of video, and regarding as material element
Frequency content.For example, step S201 in response to the operation to a video control in user interface, obtains a video segment, and
As the video content of a material element.Here, video can for example be stored in local video file, can also
It is stored in the video content in high in the clouds.For the material element comprising video content, step S201 can also add text wherein
Word content, audio content etc..When a material element includes video content, step S201 can be by the broadcasting of video content
Playing duration of the duration as the material element.
In yet another embodiment, step S201 may be implemented as the method 400 shown in Fig. 4.As shown in figure 4, in step
In rapid S401, one section of video is obtained.In step S402, according to predetermined video clipping algorithm, from this section of video extraction to
A few video segment simultaneously generates the description information of each video segment.Specifically, according to the application one embodiment, step
S402 determines at least one key images frame of video-frequency band first.For each key images frame, step S402 can be from the section
Extraction includes a video segment of the key images frame in video.The video segment can include a corresponding audio piece
Section.So, step S402 carries out Text region to audio fragment to obtain corresponding word, and according to word generation and video
Description information corresponding to fragment.It should be appreciated that step S402 can use the various algorithms for being capable of editing video automatically, the application
This is not restricted.
On this basis, in step S403, there is provided the user interface of the description information of each video segment is shown, so as to
User carries out Piece Selection according to the description information of each video segment.
In step s 404, in response to the selection operation at least one video segment, selected is each regarded respectively
Video content of the frequency fragment as a material element in material set.In other words, step S404 can will be selected each
Video segment is generated as a corresponding material element.
Illustrate in addition, be not limited by step S402 and editing is carried out to video, embodiments herein can also be to
High in the clouds sends video clipping request, and carries out video clipping by cloud device (such as server 120).On this basis, this Shen
Embodiment please can obtain the video segment of editing from cloud device.In addition, in order to which vivider explanation generation includes video
The process of the material element of content, it is illustrative with reference to Fig. 3 D and 3E.
Fig. 3 D show the user interface of the generation video segment according to the application one embodiment.As shown in Figure 3 D, window
Mouth 307 is the preview window of video to be clipped.In response to being operated to control 308, embodiments herein can generate multiple regard
Frequency fragment, such as fragment 309.Fig. 3 E show the editing interface of a video segment.For example, in response to the behaviour to fragment 309
Make (for example, click on or double-click etc.), and enter interface shown in Fig. 3 E.Wherein, window 310 for fragment 309 the preview window,
Region 311 is the description information on fragment 309.In addition, user can be inputted by word input control 312 and video segment
Corresponding word content.User can also obtain the audio content for video segment by control 313 or control 314.Example
Such as, icon 315 represents an acquired audio file.In addition, by tick boxes in operation diagram 3D, user can select at least
One video segment.So, the present embodiment can be by selected each video segment and corresponding word content and audio
Content is a material element.
To sum up, step S201 can obtain multiple material elements.Here, step S201 can be by the life of multiple material elements
Into sequentially corresponding playing sequence by default.In addition, step S201 may also respond to user's operation to multiple material elements
Playing sequence be adjusted.For example, Fig. 3 F show user circle of the regulation playing sequence according to the application one embodiment
Face.Fig. 3 F present thumbnail corresponding to each material element.Such as 316 and 317.Thumbnail is arranged in order in viewing area.
The arrangement that step S201 can adjust each element in material set in response to the moving operation to thumbnail in user interface is suitable
Sequence, and using putting in order as the playing sequence of material set after regulation.
For the material set determined in step S201, method 200 can perform step S202.In step S202, really
Fixed efficacy parameter corresponding with material set.Here, every kind of efficacy parameter corresponds to a kind of video effect pattern.Video effect example
Such as include the transitions and particle effect between adjacent material element.Wherein, transitions refers in two scenes (i.e.
Two material elements) between scene transitional effect.For example, embodiments herein can use predetermined skill (as draw as,
Dissolve, scroll), realize the smooth excessiveness of scene.Transitions is, for example, that the effect of picture into picture (is referred to as figure
Piece flies into effect).Particle effect is the animation effect of the objects such as the real reclaimed water of simulation, fire, mist, gas.Illustrate in addition, it is a kind of
